Where is the throttle body installed?

The throttle body is installed at the position connecting the air filter and the engine cylinder block. Here is some information about the throttle body: 1. The throttle body is one of the most important components in today's electronic fuel injection engine systems. Its upper part connects to the air filter, and the lower part connects to the engine block, serving as the 'throat' of the automobile engine. 2. The throttle body is slightly cylindrical in shape, with a rotating disc at its center that pivots around an axis. As the disc rotates, it controls the cross-sectional area for air passage inside the cylinder, thereby regulating the flow of the air-fuel mixture. Additional information: 1. The throttle body is a controllable valve that regulates the entry of air into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. 2. There are two types of throttle bodies: the traditional cable-operated type and the electronic throttle body. In traditional engines, the throttle body's operating mechanism works via a cable or linkage rod, with one end connected to the accelerator pedal and the other to the throttle linkage plate. The electronic throttle body primarily uses a throttle position sensor to adjust the throttle opening angle based on the engine's power demand, thereby controlling the amount of air intake.
